HANS Bl'l'CI-ILER, OF ZURICH, SWITZERLAND.

EMBROIDERY-MACHINE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed August 1'7, 1910, Serial No. 577,715. Renewed May 22, 1916. Serial No. 99,238.

To all whom it may concern:

Be it known that I, l'TANS Bi'ionLnR, a citizen of the Swiss Republic and residing at Zurich, Switzerland, have invented certain new and useful Improvements in Embroidery-Machines, of which the following is a full, clear, and exact specification.

In the known devices of this character having incoming and outgoing carriages, the attendant was heretofore obliged to closely watch the right moment during the working of the machine, for actuating the treadle mechanism and to stop the machine during such actuation.

The object of the present invention is a device for automatically actuating the treadle mechanism whenever a carriage enters.

Furthermore, the invention consists of certain other novel features and parts as hereinafter described, and more particularly pointed out in the claim at the end of this specification.

In the drawings: Figure 1 is a side elevation of the preferred form of my invention. Fig. 2 is a vertical central section thereof, and Fig. 3 is a detail view of a lever.

A illustrated in the drawing V and WV are the two carriages of an embroidery machine provided with the traverses V and W", and the levers m and f, f are connected by two pins i and 2' with a friction-disk m having on its periphery two notches, and said disk m7 engages the periphery of the friction-disk 71: which is connected with gear (Z by superposed gears 0 rotating in opposite directions and indicated in Fig. 1 by the small arrows. Iwo two-armed pawl levers o, 22 are provided and slide with their lower ends along the periphery of the frictiondisk on and flat springs 25 press said pawl levers against said disk. The upper ends of the pawl levers '0, 0 are bent and extend in the path of the actuator rods S, S if both carriages are in nearly their innermost position for actuating the nippers K which are connected to said rods S, S by suitable connections E E. The pawls 4), 22 serve the purpose to alternately check the actuation of the treadle mechanism in falling alternately into one or the other of the notches of the friction-disk m thus arresting the rotation of the same as soon as the treading is finished.

The rods S and S disengage at the entrance of their carriages the pawls o and 01 and the friction-disk m so that the latter in consequence of its frictional connection with disk is is turning in the opposite direction and moves the levers m and f, f into their other end position. This effects in a similar way as described above the actuation of the treadle mechanism of an embroidery machine. At the end of the actuation of said treadle mechanism either one or the other of the parts v, '0 enters the corresponding notch of the disk m and stops the rotation of the same.

Having thus described my invention what I claim is An embroidering machine comprising in combination, treadle mechanism, incoming and outgoing carriages, traverses upon said carriages, a friction disk having notches in its periphery and operatively connected with said treadle mechanism, pawls engaging said notches to check said mechanism, and means actuated or carried by the carriages for disengaging said pawls on the entering movement of the carriages, substan tially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
